The score for reaching the cage depends on the time that it took to reach the key: fast run gives 20 points, slow run gives 5 points. Opening the last part gives an extra 20 points.

At 300 points you enter 'chance time'. If you have no misses at that point, all points you score will be doubled until you make the first miss. If you have misses at that point, all misses will be cleared.
